I bought the Bog and Wendigo skin packs for the monsters and they show up for Goliath and Kraken, but I still don’t have the ability to customize Wraith. I am on the Xbox One and have the Ultimate edition.

From the home screen press ‘menu’ on evolve and go to ‘manage game’. Go all the way right and look under ‘ready to install’. Don’t know whether it will be there but it’s worth a try. I hope this helps.
